I have QB 2019 as well, with the same problem as everybody else. I looked into returning to the Ventura OS. Apple said the only way to do it is to wipe your computer, then install a pre-Sonoma backup. Rather than going through that, I'm gonna wait. In the meantime, I used Adobe to edit all my last month invoices in order to bill my clients for October. Once QB is fixed, I'll need to go in and enter everything I handled outside the system. What a mess.
